it depends how old you are.
23-15=8 no matter what you try to make us believe, is not okay.
Still the same # for me, 31.I thought it was like 1/2 your age + 8.
Example: 30/2=15+8=23. A 30 year old can date a 23 year old.
It just occurred to me that in any large age differential, there is a cradle robber AND a grave robber involved.
